Personally, I keep a low bandwidth stream of thoughts on Twitter, my professional
profile at LinkedIn.
Twitter is probably the easiest way to get in touch with me, but if
you want to send an email my address is my first name at this domain.
If you want to send something privately, use my key from keybase.io/calmh.
